look here my gas gauge quit working. put new fuel pump in it still no go. Do not know if it has anything to do with it. but brake light and abs comes on to.the gas gauge works once in a blue moon. abs comes on and off. what do you think could be wrong?

 

a number of things, did you replace the whole pump/sender assembly or just the pump? and the other lights may or may not be related you could have a ground or cluster issue but without knowing the vehicle or history its like chasing a fart in the wind
